However, when using the electric starter, the possibility of hydro-locking is possible. (Hydro-locking is a condition where too much fuel is in the combustion chamber or other cavities of the engine. So much so that attempting to force the engine to turn over will result in damage.) Always “pull” the propeller through the compression strokes 2 or three times with the power for the glow plug disconnected to check for a hydro-locked condition before applying the starter.
